Using a white cow as her reference image, Dianne guides us through an exercise where she begins by locating all shadow areas via the terminator. Using that area of division, she creates a solid “wash” over all shadow areas. Then she locates and defines deep,
moderate, shallow and core shadows and distinguishes form shadows from cast shadows. Finally, she lifts out reflected light. Doing this drawing exercise, one can gain an understanding of how shadows behave and how we can render them with ease.
